Liquid Cooling System

Gravity-driven two-phase liquid cooling systems using flow boiling within micro-scale evaporators are becoming a game-changing solution for electronics cooling. The optimization of the system’s filling ratio can however become a challenging problem for a system operating over a wide range of cooling capacities and temperature ranges. The benefits of a liquid accumulator to overcome this difficulty are evaluated in the present paper. An experimental thermosyphon cooling system was built to cool multiple electronic components up to a power dissipation of 1800 W. A double-ended cylinder with a volume of 150 cm3 is evaluated as the liquid accumulator for two different system volumes (associated to two different condensers). Results demonstrated that the liquid accumulator provided robust thermal performance as a function of filling ratio for the entire range of heat loads tested. In addition, the present liquid accumulator was more effective for a small volume system, 599 cm3, than for a large volume system, 1169 cm3, in which the relative size of the liquid accumulator increased from 12.8 % to 25% of the total system’s volume.

Liquid Cooling System

Gravity-driven two-phase liquid cooling systems using flow boiling within microscale evaporators are becoming a game-changing solution for electronics cooling. The optimization of the system's filling ratio (FR) can however become a challenging problem for a system operating over a wide range of cooling capacities and temperature ranges. The benefits of a liquid accumulator (LA) to overcome this difficulty are evaluated in the present paper. An experimental thermosyphon cooling system was built to cool multiple electronic components up to a power dissipation of 1800 W. A double-ended cylinder with a volume of 150 cm3 is evaluated as the LA for two different system volumes (associated with two different condensers). Results demonstrated that the LA provided robust thermal performance as a function of FR for the entire range of heat loads tested. In addition, the present LA was more effective for a small volume system, 599 cm3, than for a large volume system, 1169 cm3, in which the relative size of the LA increased from 12.8% to 25% of the total system's volume.
